UNIVERSAL VISE AND VISE JAW.

Application filed December 16, 1919. Serial No. 345,218.

To all whom it may concern:

Be it known that 1, WILLIAM GUsrAVE BLoMsTnAN, a citizen of the United States, residing at 606 Spies Avenue, Menominee, in the county ofMenominee and State of Michigan, have invented certain new and useful Improvements in Universal Vises and Vise Jaws, of which thefollowing is a specification.

My invention relatesto improvements in. universal Vises, the vise holder therefor, and the auxiliary vise jaws which are in conjunction therewith; and the objects of my improvements are, first, to construct a vise which will be wholly universal in its scope in the vise holder therefor; second, to so con struct a universal vise holder which will efficiently hold the vise in any desired position convenient to the worker, by simply placing the vise in that position desired and securing it there, by the turning of a thumb screw, as indicated in Figure 5, of the drawings; third, to provide a pair of auxiliary vise holder jaws, which are so constructed thatthey will' receive the vise, containing my improvements, in any desired position therebetween, and, be clamped together upon the vise, in between the jaws of another vise, for instance, of the present make Vises which may be, or are, already installed; fourth, to provide a movable, or clamping jaw, slidably. mounted on the lower, or stationary held jaw, and, means in the upper, or movable clampingjaw, for clamping the piece to be worked uponbetween the component jaw faces of said movable and stationary held jaw; fifth, to provide auxiliary universal counter-part circular dovetail vise-jaws between which can be clamped various shaped articles, and also, the said jaws may be turned and clamped in the desired position most convenient to the worker.

These, and other objects of my improvements will be more clearly pointed out in the mechanism illustrated in the accompanying drawings, and more fully described in the following specification and appended claim. 1

In the accompanying drawings Figure 1, is a side view of my invention containing my improvements. embodied therein; and shows it resting on a bench which is indicated by light dotted lines.

, Figure 1 is a section on line B-B of Figures 1 and 2. j

Figure 2, is a side view of my improved vise wherein the auxiliary universal circular dovetail counter-part vise'jaw members jaws shown separated from each other and,

as installed in the movable clamping jaw member and the lower or stationary member of the vise embodying my improvements; after-parts of the visemembers being broken away.

Figure 5, is a side View ofa universal vise holder, whereinis held my universal vise (only a part of which is shown), and, in

which, are embodied the improvements as contained in my invention. 7

Similar characters refer to similar parts throughout the several views.

In Figure 1, will be seen the lower, or, stationary, vise member, 6, resting on a table, or bench, 7, and supporting a sliding, or, movable clamping vise member, 8; and,

to each of the members, 6, and, 8, are secured, respective jaw plates, 6, and 8. In both the Figures, 1 and 2, it will be seen that the jaws of the vise are in the closed position. And, it will be particularly noted,

in Figures, 1, '2 and 5, the comparatively large amount of open space, 9, there is within the upper and lower members, 8 and 6. This feature as embodied in the construction of the vise, permits of the clamping between the jaws thereof, a comparatively greater variety of articles, of, not only in size, but, in shape as well. On the upper part of the vise member, 6, at, 10, are

angular shaped grooves or ratchet teeth, which receive therein similar teeth, 11, of a pivotally secured clamping member, 12, which has a hand-grip, 13, formed thereon. And, hingeably secured within the member, 8, on the pin, 14, which is mouted in bearings, 8", of the member, 8, is another clamping member, 15, and, hingeably secured to the free end of the member, 15, on a pin, 16, which is mounted therein, is another clamping member, 17, and, to the free end of this member, 17, is pivotally secured on the pin, 18, which is mounted therein, the toothed clamping member, 12. These members 12, 15, and 17, together with the hand-screw, 19, constitute the clamping means previously mentioned. And as the arrangement of the members, 15 and 17 form a toggle-joint, and with the aid of the hand-screw, 19, a great clamping pressure can be obtained with but very little effort on the part of the worker when securing the piece in the vise; and, it can be readily seen, that, with only a few releasing turns of the screw, the piece in the vise will be released, and the jaw, 8, can be. moved away, quickly, by simply pulling on the hand-grip, 13, with the fingers and pushing against the boss, 20, with the palm of the hand. And, from the foregoing, it can be readily understood that the jaw, 8, can be moved forward, or backward,

at will, and be set, in a jiffy, to aceommodate any sized piece, within range of the vise. By referring to Figures 1 and 2, it will be seen that there are three teeth, 11, in the underside of the member, 12, of which, two are shown to the left of the center-line A-A, and the remainder to the right thereof; the object of this arrangement, is to prevent the member, 12, from turning over on its axis when clamping the work between the vise jaws.

On the underside of the lower, or stationary jaw, 6, will be seen secured thereto, and, which is a part thereof, a spherical knob, 21; and, the purpose of this knob, 21, is to give to the vise that 2 universal feature which forms one of the improvements embodied in my invention. And, the application of that feature can be seen and fully appreciatec by referring to Figures 2 and 5, where it will be noticed held between a'pair of half spherical socket jaws, 22 and 23, 24 and25, respectively. The jaws, 22 and 23, are held together by means of three screws, 24, and springs, 25; and each half jaw, 22 and 23, have a ledge, or flange, 26 and 27, respectively, formed thereon, so that they rest on the jaw plates, ,8 and 6 when the said jaws 8 and 6 are slightly released to permit of the turning; of the vise, shown in Figure 2, to any desired angular position most suitable and convenient to the worker.

In the vise members, 6 and 8, are revolubly secured, two circular dovetailed half jaws,

28 and 29, respectively, which, also may be turned at any angle to suit the work that may be placed therebetween, or, to accommodate the convenience of the worker. As,

for instance, the angular positions indicated in Figure e, by the light dot and dash lines CC and C-C, or D-D and D-D, or CC and 11-1).

In Figure 5, will be seen secured between the half spherical socket jaws, 24c and 25, the spherical knob member, 21, of the vise jaw, 6. The half jaw, 24, isformed in the upper part of the upright, 30, which has a base, 31, sufficiently broad enough to prevent its falling over when an article is clamped in the vise, and work being performed thereon. The half spherical socket jaw, 25, is formed in the upper end of a hinged vise clamping lever, 32, which is hingeably secured on a hinge pin, 33, secured in the bearing, 34, in the upper part of the upright, or stand, 30. On desiring to change the position of the vise secured in thejaws, 2d and 25, to more conveniently accommodate the worker, all that is necessary for him to do, is to unscrew the thumb-screw, 35, slightly, and setthe vise in the position so desired and reclamp it there, so placed, by simply turning the thumb-screw, 35, against the flange, 36, of the stand, 30; and this can be done, without the least effort at all on the part of the worker.

The side views of both Figures 1 and 2, and the cross section shown in Figure 1 show a dovetail slide, 37 over which fits a counterpart dovetail, 37. formed in the lower part of the sliding jaw 8; and, it will be seen by again referring to Figures 1 and 2, that the said dovetail portion is, comparatively, ofv a suflicient length to hold it in proper alignment when a piece of work is clamped between the jaws of the vise; and, also, when moving said jaw, 8, forward or backward, there will not be any cramping or hindrance to the operator.

Having thus described my invention, the merits of my improvements can be readily understood, and it will be seen that the minor details of my construction may be 1 altered in many ways without departing from the spirit of my invention, therefore, what I claim and desire to secure by Letters Patent is t The combination in a universal vise, of the class set forth, a. stationary held vise member provided with a spherical member and a longitudinally slideable rear clamping jaw, Ya vise-jaw clamping means, located in the longitudinally slideable rear clamping jaw, consisting of a toggle-joint operatively controlled by a hand screw threaded into. the upper part of said slideable clamping jaw, and, one of the members of said toggle-joint adapted to engage angular notches formed .in the upper portion of the tail end part of the lower or stationary vise member, and, means on the notch engaging member of said toggle-joint for disengaging same from engagement With thenotches in the said lower vise portion; afloor stand having tWo half component counterpart spherical socket clamping jaws mounted in the upper end thereof to receive the spherical member mounted on the underside of said stationary held vise jaw.
